Potassium and Sulphur Response on Productivity of Forage Berseem

Berseem clover (Trifolium alexandrinum L.) belongs to leguminous family It is rich in protein and the other total digestible nutrients, as well as carotenes and minerals; it is very nutritious, succulent, palatable and high yielding valuable leguminous crop. The nutrient element of major significance for yield and quantity of Berseem are nitrogen, phosphorus and sulphur. Its importance in agriculture has increased with intensive agriculture due to acceleration in native K mining which is resulting in inadequacy in crop plants. This plant is among the most valuable forages available for stock feeding. The protein percentage of berseem clover has been reported as much as 20.96%. The typical method of nutritional provision is using chemical fertilizers. Indiscriminate usage of chemical fertilizers not only does increase the production costs, but also leads to contamination of agricultural ecosystems.
